Abstract
It was investigated that the effects of preparation methods and conditions for SrFeCo0.5Ox dense membrane on their oxygen permeability. Three different methods, a solid-state reaction method, an evaporation-to-dryness method, and a combined citrate and EDTA complexing method, were applied for the preparation of parent powder. The oxygen flux through membrane at 900 °C was increased in the order listed above. The oxygen flux could be greatly improved by repeated calcination and grinding of parent powder. The membrane sintered at a temperature as high as 1200 °C showed a higher oxygen flux (0.22 cm3 (STP)/cm2 min).
